چکیده

In the title compound, C(12)H(14)N(2) (2+)·2I(3) (-), the 1,1'-dimethyl-4,4'-bipyridinium (DMBP) dication is charge balanced by two triiodide ions. The DMBP dication is planar within 0.010 (5) Å. The asymmetric unit contains only half of the dication, the other half being generated by an inversion center. Weak C-H⋯I inter-actions link the ions into sheets parallel to (121).

Two New Polyiodides in the 4,4′-Bipyridinium Diiodide/Iodine System

The reaction of bipyridine with hydroiodic acid in the presence of iodine gave two new polyiodide-containing salts best described as 4,4′-bipyridinium bis(triiodide), C10H10N2[I3]2, 1, and bis(4,4′-bipyridinium) diiodide bis(triiodide) tris(diiodine) solvate dihydrate, (C10H10N2)2I2[I3]2 · 3 I2 · 2H2O, 2. Both compounds have been structurally characterized by crystallographic and spectroscopic ...

1,1′-Dimethyl-4,4′-bipyridinium bis­(tetra­fluorido­borate)

In the title compound, C(12)H(14)N(2) (2+)·2BF(4) (-), the cation has a centre of symmetry at the mid-point of the central C-C bond. π-π inter-actions, with a shortest atom-to-atom distance of 3.757 (4) Å, extend the crystal structure into a one-dimensional supra-molecular chain.

Formation of Triradical Trications from Hexaquaternary Salts Derived from 4,4'-Bipyridine

We recently reported the preparation of tetraquaternary salts derived from 4,4'-bipyridine of the type (1; R = Me or Et, n = 2 ,3 or 4) [1], and showed that they were reversibly reduced to diradical dicat­ ions (2; R = Me or Et, n = 2, 3 or 4) by the uptake of two electrons. Reversible redox systems of this type are of interest as components of electrochromic memory display devices [2—5], as bi...

In the title compound, [N(C(4)H(9))(4)][V(C(23)H(21)NS(3)Si)(2)]·4CH(3)CN, the V(III) atom (site symmetry ) is coordinated by two N,S,S'-tridentate 4,4'-dimethyl-2,2'-(3,7-dimethyl-1H-4,2,1-benzothiaza-siline-1,1-di-yl)dibenzene-thiol-ate ligands in a distorted trans-VN(2)S(4) octa-hedral geometry. The complete cation is generated by crystallographic twofold symmetry, with the V atom lying on t...
